With scientific information suggesting a potential risk of future ozone depletion with continued growth in use and emissions of CFCs and other ozone depleting gases, countries negotiated and agreed to the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. The Protocol originally called for a 50% reduction in consumption (use) of CFCs in developed countries by 1999. When subsequent scientific assessments showed that ozone depletion was occurring, and projections suggested even more depletion would occur under the initial Protocol controls, the controls were modified to phase out all compounds with significant potential to deplete the ozone layer. These phaseout schedules were formulated based on the relative ability of compounds to impact the ozone layer (known as “ozone depletion potentials” or ODPs). Compounds with higher ODPs were placed on faster phaseout schedules.

The Protocol phaseout schedule for CFCs and HCFCs in developed countries (termed “Non-Article 5(1) Parties”) and developing countries (termed “Article 5(1) Parties”) are shown in the following tables:
